Is a 4GB iPhone headed to Wal-Mart?

Word on the street is that Wal-Mart may soon be selling a 4GB iPhone for just $99. The information came to the Boy Genius Report via a tipster who doesn’t have much credibility (so take it as the world from the street corner or maybe a dark alley). While most experts are discounting the probability of a Wal-Mart exclusive phone (why would Jobs offer a cheaper version of his product in just one store and not his own?) it may indicate that a smaller, less expensive iPhone is on the horizon. The phone wouldn’t be big enough to store much music or many videos, but for people just interested in email and web browsing it could be a great option to have available [via BoyGenius]
